A method and apparatus for a reusable resin distribution line for use in conjunction with a resin transfer molding apparatus is disclosed. The apparatus includes a soft tool and a hard tool (i.e., mold). In the illustrative embodiment, two inflatable bladders are disposed on a side of the soft tool, wherein a bridge spans the bladders.
